Abstract: An assembly for detecting defects on a bodywork of a motor vehicle that includes a gantry, of inverted U-shaped cross section, shaped to allow the passage of the motor vehicle in a longitudinal direction, from the rear of the gantry to the front of the gantry. The gantry includes an inner surface extending transversely between two lateral free ends and includes a light source suitable for illuminating, in a substantially uniform manner, the bodywork of the motor vehicle during its passage, the gantry including at least one opaque strip extending transversely over the entire length of the inner surface. The assembly includes a plurality of cameras installed at a distance from the gantry, in at least one longitudinal direction, so as to capture images of the bodywork of the motor vehicle during its passage under the gantry, and a detection member suitable for receiving the images captured by the plurality of cameras and for detecting, according to these images, defects in the bodywork, by analyzing the reflection of the opaque strip on the bodywork and by directly recognizing, in the images, defects on the bodywork.
